newton's laws of motion vocabulary Flashcards
force
A push or a pull exerted on an abject in order to change the motion of the object.
motion
a change in position over time.
net force
the combination of all the forces acting on an object.
speed
distance traveled per rate of time.
velocity
the speed and direction of an object
acceleration
the rate at which velocity changes over time
Newtons first law
an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside.
newton’s second law
force=mass x acceleration
newton’s third
for every action there is an equal but opposite
inertia
the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction
friction
a force that resists motion
Mass
The amount of matter in an object.
gravity
An attractive force that exists between all objects that have mass.
gravity
An attractive force exists between all objects that have mass.
